Rhizome creeping, iiairy; stipes not articulate to it; fronds simply 

 pinnate: veins anastomosin;,'. without free included veinlets; sori linear, 

 about midway l)etween niar^'in and co.stu, iisually uninterrupted. Terres- 

 trial ferns of moderate size. Not very evidently related to its neighbors 

 here, and i)erhaps better transferred witli I'ldti/lnrnid to the neighborhood 

 of (.{ymnopteris.

Platytaenia requiniana ((Jaud.) Kuhn is a fern very like Tornitis in 

 its vegetative characters, but with the entire back of the contracted fertile 

 frond covered by sporangia. From tlie meager descriptions it seems likoly 

 to me that it is a (!ii»\)ioi)teris. but Diels ])laees it next to Taciiifis.
